Lesson 1.3 leads you through the creation of a Java™ method.
In this lesson you will
- Create a Java method
- Create the input and output data mapping between COBOL and Java
- First you will create a Java method: In the Project Explorer
view, expand the project InOutArray in Dynamic Web
Projects.
- Right-click on InOutImpl.java in JavaSource,
and select Source > Add method to J2C Java bean.
- In the Java Method page, click Add.
- In the Java method name field, type runInOut for
the name of the method.
- Next you will create the input data mapping between COBOL and Java: Beside
the Input type field of the Java Method page, click New.
- In the Data Import page, ensure that the Choose mapping field
is COBOL to Java. Click Browse beside
the COBOL file field.
- Browse to find the file location of the InEqualsOut.cbl file. (You
can find a copy in your product installation folder: <installdir>\IBM/SDPShared/plugins/com.ibm.j2c.cheatsheet.content/Samples/\IMS/InOutArray).
- Click Open.
- Click Next.
- In the COBOL Importer page, click Show Advanced.
- Select the following options:

- Click Query to load the data.
- A list of data structures is shown. Select IN-OUT-MSG in
the Data structures field.
- Click Next.
- In the Saving Properties page,
- Select Default for Generation
Style.
- Click Browse beside the Project
Name and choose the Web project InOutArray.
- In the Package Name field, type sample.ims.data.
- In the Class Name field, accept the default INOUTMSG.
ClickFinish.
- Leave the Save session as Ant script unchecked.
- In the Java Method page, select Use input type for
output.
- Click Finish.
- Click Finish to complete the definition
of the method.
